Role of Hydrophobic Effect on the Noncovalent Interactions Between Salicylic Acid and a Series of beta-Cyclodextrins.

Abstract

The molecular complexation of salicylic acid (o-hydroxybenzoic acid) by beta-cyclodextrin (beta-CD) and/or two of its most used derivatives, 2,6-di-O-methyl-beta-cyclodextrin (DIMEB) and hydroxypropyl-beta-cyclodextrin (HPBCD), was studied from pH potentiometric measurements. The role of the hydrophobic effect was evaluated by studying the influence of the… (More)
